Yes, lets run down the arguments in the article:
"It's obvious from my email today that this icon and MS pitch alone are confusing many users."
Ok, this actually has nothing to do with Windows 10 itself. It's a valid point as far as it goes, but how exactly was MS supposed to inform the affected users that the Windows 10 update was available?
"If you decide you do not wish to upgrade to Win10 now, you may want to get rid of that notification. MS doesn't tell you how (surprise!) and the procedure can range from relatively simple to "a real mess" "
Again, not actually about Windows 10. In fact it's about how to avoid Windows 10, which MS wants people to see as simply another update a la "Update Tuesday", though granted a major one.
"Many users -- especially on somewhat under-powered systems -- may find Win10 to be a painfully slow experience compared with Win7, irrespective of MS' claims."
Big citation needed. There's no evidence that Windows 10 performs worse on low power systems and there's significant evidence that it performs better.
"Worse, some functionalities important to many users are missing. If you use Windows Media Center -- that's gone from Win10. DVD playback is currently problematic."
I guess I don't know about this one. I do know I was able to play DVD's on the technical previews without issue.
"And here's a biggy. If you don't want Microsoft installing updates automatically -- if you're a user who has chosen to take control of this process up to now -- you probably will hate Win10."
Ok, here we have arguably the first real problem. MS has botched Windows updates in the past. Being able to block them and roll them back is how those situations have been limited and fixed. Lumping drivers into this forced upgrade schedule... as a laptop user this makes me nervous. Laptop drivers can be quite finicky and I don't always blindly trust newer versions when they land.
"In some environments, this is unacceptable from a support and security standpoint, and reports are already coming in regarding driver related issues."
Going back to FUD again... the automatic, unblockable upgrades only applies to Home users. If you're using Home editions in a corporate environment you're gonna have a bad time. It's also probably against your license agreement and can land you in trouble (right or not) with the licensing boards.
We're back on track! This is a real issue potentially. I'd prefer this were more explicitly spelled out during install and the user given more fine grained control over things. Sending all your docs and data to a 3rd party by default without informed consent should be illegal IMO. The fact that you can turn the features off mitigates things, but doesn't really solve them.
